# hu13 container entrypoint (f0rge issue #11): build once, then serve.
#
# Layout: the repo is mounted read-only at /data/repo, the inbox lives at
# /data/inbox (OUTSIDE the served tree — serve refuses to start otherwise),
# the built site goes to /srv/www.
#
# Env:
#   HU13_BRANCH     branch to build (default: main/master auto-detect)
#   HU13_CLONE_URL  clone URL to advertise (default: repo origin remote)
#   HU13_PUBLIC_ORIGIN public base URL of this server (default: unset;
#                   when set, clone block advertises `<origin>/repo.git`)
#   HU13_REPO_NAME  repo display name (default: repo dir name; never blank)
#   HU13_DESCRIPTION
#                   site description (default: hidden, no empty <p>)
#   HU13_LISTEN     serve address (default: 0.0.0.0:39313)
#   HU13_MAX_TITLE / HU13_MAX_BODY / HU13_MAX_BYTES /
#   HU13_RATE_PER_HOUR / HU13_QUOTA
#                   inbox caps (serve defaults when unset; passed through
#                   as flags only when set, env is the fallback otherwise)
#
# Fail loud: any build failure (bad branch, bad repo, missing dir)
# aborts before serve starts. `serve` is exec'd so it keeps PID 1.
